Add Price Line

A price line is a horizontal line drawn across the width of the chart at a specific price value. This example shows how to add price lines to your chart.

Short answer

A price line can be added to a chart by using the createPriceLine method on an existing series (ISeriesApi) instance.

const myPriceLine = {
    price: 1234,
    color: '#3179F5',
    lineWidth: 2,
    lineStyle: 2, // LineStyle.Dashed
    axisLabelVisible: true,
    title: 'my label',
};

series.createPriceLine(myPriceLine);

You can see a full working example below.

Tips

You may wish to disable the default price line drawn by Lightweight Charts™ for the last value in the series (and it's label). You can do this by adjusting the series options as follows:

series.applyOptions({
    lastValueVisible: false,
    priceLineVisible: false,
});

How to use the code sample

The code presented below requires:

• That createChart has already been imported. See Getting Started for more information,
• and that there is an html div element on the page with an id of container.

Here is an example skeleton setup: Code Sandbox. You can paste the provided code below the // REPLACE EVERYTHING BELOW HERE comment.
